Agreed. He'd be fine in the summer time, but winter would be another matter. Definitely choose the heat pump instead of resistance heating if it's an option (not sure if option or standard equipment on all Bolt trims).
RE: Bolt for a ~200 mile commute, in the north:
-I don't believe Bolt uses a heat pump, for heat (typical for A/C, but in reverse).
-Volt2 came out, and they increased the kw of its resistance heater. Volt1 could soak over 5,000 watts (heats the battery coolant loop, then cabin)
-The thing with Volts, especially for someone from Plymouth MA going long in their commutes, is to remember the thermostat on the engine opens (or used to) at about .1 gallon. Then, you've got gobs of heat for the cabin, and you can keep the watts for driving instead. You have to time your use of 'Hold' mode, like as the first thing on a freezing day. (my wife never got used to this/figured it out, and benefited from automatic engine operation below 36 degrees)
Long Range EV's (Bolt) don't suffer the same cabin heating losses other PHEVs do. "Range fell 40%" is a common complaint from battery-only heat, but it's kwh that heat the car, not "% of range". Once you get up to 60kwh, the percentage is not that bad. Will a 238 EPA AER rated car deliver heat and 200 miles? It could be close, or possibly worth pulling the trigger if those <2 weeks/year, where its <15 degrees, are times where a fast DC station can be found along your path. Enough to be on your way, wouldn't take more than a gas stop. It's just you'd have to do it a ~dozen+ times a year. ....not necessarily a bad trade versus gassing up year round.
